Wolf Trimboards are made from high-cell-density PVC that the company says will not absorb moisture and keeps the boards from swelling, rotting, splitting, cupping, or delaminating when exposed to the elements. The trim can be routed, mitered, and heat-formed, and can be cut, drilled, nailed, and glued with regular tools. It is available in smooth-matte or wood-grain finishes, or can be painted for a customized look. Pricing available only through distributors. wolfhomeproducts.com
